Adding more hashtags to Instagram posts doesn't tend to help boost views, according to recent research from Social Insider.

The report was based on data from 75,361,233 Instagram posts published between March 2021 and March 2022. To understand the relationship between hashtags and views, the researchers calculated the average engagement rate (likes and comments) by impressions for posts with different numbers of hashtags.

The researchers found that although hashtags are useful for categorization and discovery, they don't have a major influence on distribution. There was no significant difference in the average engagement rate by impressions for the Instagram posts analyzed, regardless of how many hashtags those posts had.

The researchers found some differences depending on Instagram account size (number of followers).
